It aligns site execution with the documented scope and acceptance expectations.
Who uses this method statement
This method statement is used by contractors, site supervisors, project engineers, QA/QC engineers, HSE officers, consultants, and client representatives. It serves as a shared reference for planning, execution, supervision, inspection, and approval of the activity on site.
When it is prepared and submitted
The method statement is prepared before the work activity starts and submitted as part of the pre-construction documentation package for review and approval.
Who reviews or approves it
The method statement is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the work commences.
Important approval note
This method statement is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all content must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.
For example: if your specification requires a departure from a referenced standard, that departure must be documented and approved separately — this method statement will not capture that automatically. Always verify against your applicable drawings, specifications, and regulatory requirements.

| 3 | Moisture and pH checks | Measure substrate moisture using pin moisture meter at representative points (min 1 per 20 m², each wall/ceiling). For cementitious bases conduct ASTM D4263 plastic sheet test as indicative check. Measure surface pH with strips moistened with DI water. | QC Engineer | On-site tests |
| 4 | Repairs and crack treatment | Cut and widen cracks to V-groove (~3–5 mm), remove dust, prime if required, fill with polymer-modified repair mortar. For non-structural cracks, embed alkali-resistant mesh/joint tape in base skim layer. | Skilled Plasterers | QC check before covering |
| 5 | Masking and protection | Mask junctions, trims, sockets, and protect floors/adjacent finishes. Install corner beads if specified. | Helpers / Supervisor | Visual |
| 6 | Priming/bonding (if required) | Apply manufacturer-approved primer/bonding agent to high-suction or low-porosity substrates. Allow to dry per PDS. | Skilled Plasterers | QC verification |
| 7 | Mixing of skim coat | Measure clean water to PDS ratio (typ. 0.30–0.35 w/p by weight for cement skim; gypsum per PDS) [Verify]. Add powder to water, mix 2–3 min to lump-free paste, rest (slake) 2–5 min, remix 30–60 s. Do not re-temper after pot life (typ. 60–90 min) [Verify]. | Skilled Plasterer | Supervisor oversight |
| 8 | First coat application | Apply thin coat using stainless steel trowel at ~1–2 mm. Work wet-on-wet to maintain open time. Level using 2 m straightedge; feather at edges and around openings. | Skilled Plasterers | In-process |
| 9 | Drying/curing control of first coat | Allow to firm up; avoid forced drying, direct sunlight, or strong airflow. Use dehumidifiers/air movers only as allowed by PDS. Typical recoat time 4–24 h depending on product and conditions [Verify]. | Site Engineer / Supervisor | Env. monitoring |
| 10 | First coat inspection (HP2) | Check flatness with 2 m straightedge, defects/voids, pinholes. Touch-up low areas before second coat. | QC / Consultant | Hold point inspection |
| 11 | Second (finish) coat application | Apply finishing coat ~0.5–1.5 mm to remove tool marks and achieve paint-ready smoothness. Re-level; burnish lightly only if permitted by PDS. | Skilled Plasterers | In-process |
| 12 | Final drying/curing | Allow to dry fully prior to sanding/painting. Typical full dry 12–48 h depending on product, thickness, and climate [Verify]. Prevent condensation and dust deposition. | Supervisor | Env. monitoring |
| 13 | Sanding and finishing | Dry sand with P180–P240 abrasives using dust-extraction sander; avoid over-sanding. Remove dust with HEPA vacuum and tack cloth. | Skilled Plasterers | In-process |

Frequently asked questions
Per manufacturer guidance, each pass is typically 1–3 mm with a total build of about 2–5 mm. Verify against the specific product data sheet.
Use a pin-type moisture meter and, for cementitious substrates, the ASTM D4263 plastic sheet test as an indicative check. Acceptance is typically ≤5% moisture by weight [Verify].
For high-finish areas, a typical benchmark is ≤2 mm deviation under a 2 m straightedge; ≤3 mm may be accepted for standard areas [Verify per project specs].
Not always. Primer or bonding agents are required on dense, low-porosity, or high-suction substrates when recommended by the skim coat manufacturer.
Only when specified by the project or for critical areas. Use EN 1542 with a typical acceptance ≥0.5 MPa, or per project requirements.
